Question

A car moving with a velocity of 36 km / hr is brought to rest in 5 second by applying broken find the retardation applying on it

Answer 1

Answer:

put the diatance formula and solve it mate

Answer 2

Explanation:

Given ;u=36km/hr=36×(5/18)=10m/s

and t=5sec

use newtons eqn if motion

v=u+at

here v=0; as car is stopped

so 0=10+a×5

5a= -10

a= -2m/s2

hope it helped .
